To all whom it may concern:

Be it known that I, LEONARD O. PACKARD, a citizen of the United States," residing at Needham, in the county of Norfolk and State of-Massachusetts, have invented an Improvement in Duplicating Devices, of which the following is a specification.

This invention relates to duplicating devices especially designed for the use of children in repeatedly tracing maps, to better enable them to carry in their minds the general outline of difierent countries, States, etc., yet they may be put to many other uses, as for instance, to duplicate patterns, etc.

The device comprises a sheet of paper or like material having portrayed thereon a map or other figure pattern or design, and a transfer-sheet arranged beneath said figured-sheet, and a backing-sheet arranged beneath said transfer-sheet. The figuredsheet and the transfer-sheet are attached together at both ends, and the backing-sheet is attached to the aforesaid sheets at its upper end only, thu's admitting of the interposition of a sheet to be operated upon between the transfer-sheet and the backingsheet. The means employed for attaching the sheets together is detachable, so that the transfer-sheet may be shifted with respect to the figured-sheet, and replaced by new sheets, when desired, and the figured-sheet may be replaced by other figured-sheets when desired.

Figure 1, is a perspective view of a duplicating device embodying this invention, the corner of the transfer-sheet andof the figured-sheet being raised to expose the sheet which is being operated upon and also'the backing-sheet. Fig. 2, is a sectional detail on the line 22, Fig. 1.

The sheet 1 is or may be composed of paper of a good quality, which will admit of a map or other figure, pattern or deslgn, which is printed or otherwise portrayed thereon, being repeatedly traced by means of a pointed instrument without puncturing or breaking it. Ordinary paper of a good quality may be repeatedly traced twentyfive or more times.

The sheet 2, is the transfer-sheet, which is composed of thin paper having a transfer surface applied to its underside or that side away from the figured sheet 1.

The sheet 3, is the backing-sheet, which is, or may be composed of paper of agood quality and having a hard surface to serve Specification of Letters Patent.

as a smooth, hard surface or foundation upon which the sheet to be operated upon is placed by which to enable the transfer lines to be sharp or well defined.-

The several sheets may be made of the same size, although if desired, the backingsheet may be made longer than the other sheets.

As the device is designed primarily to be placed in the hands of children it is very desirable that the transfer-sheet shall be concealed and securely held in its place of concealment, and for this reason, it is attached at both its upper and lower ends to the figured sheet. When thus disposed and secured, the two sheets may be manipulated as one.

The sheet 4, of paper to be operated upon,

the child, a very accurate outline will be obtained which will be carried in his or her mind.

In view of the fact that the figured-sheet Wears out when. repeatedly traced, and also that it is liableto be accidentally punctured or torn by the pointed instrument, it is a distinct advantage to provide means Whereby said sheet may be replaced by a new sheet; furthermore when the transfer-sheet hasbeen used repeatedly several times it becomes useless, although by shifting it a little with respect to the figured-sheet, it is as good as new, hence it is a distinct advantage to provide means for-enabling the transfersheet to be shifted, or, if desired, to be replaced by a new sheet. Herein these results are obtained by providing detachable means for attaching said sheets together at both ends, and said means is here shown as detachable fasteners 5. These same fasteners will be employed for attaching the backingshtleet to the aforesaid sheets at its upper end on It will be observed that my device is fully prepared for the use of the child, and all that is required for the child to do is to place the sheet to be operated upon between the transfer sheet and the backing sheet. No

skill, or reasoning is required, there being.

only one place that this sheet can be interposed.

I claim A duplicating device consisting of a sheet having portrayed upon its outer surface a figure, pattern or design, a transfer-sheet arranged beneath said figured-sheet, and a backing-sheet arranged beneath the transfer-sheet, said figured-sheet and transfersheet being attached together at their lower ends by detachable means, and all of said sheets being attached together at their upper ends by detachable means, thus permitting of the interposition of a sheet to be operated upon between the transfer-sheet and back- 20 LEONARD O.
